Jonah Hessels

Jonah brings a range of analytical and engineering skills to his role as senior associate. In nearly five years at Cadeo he has honed his project management and market research experience, leading project teams and testing novel market research approaches that address persistent data gaps. This, combined with his engineering background, results in well-documented, scalable research protocols that can be replicated to inform on-going market tracking. Jonah’s experience ranges from systematic compilation of publicly available HVAC permit data to mystery shopping to investigation of market effects from residential water heater standards. Mr. Hessels is a natural collaborator and data driven thinker who balances his passion for engineering analysis with a love for building strong relationships with coworkers and clients.

Prior to joining Cadeo, he developed power take off systems for offshore ocean wave energy converters at KRISO Ocean Engineering and served as a lead technical researcher with MIT’s Sport Technology Group where he partnered with the P.G.A to analyze golf teaching tools. Jonah received his B.S. in mechanical engineering from Massachusetts Institute of Technology. He is also an active member of the D.C beekeepers alliance and a guest lecturer in the University of D.C’s beekeeping course.
